If Z=sqrt(R^2+X^2), then Z=sqrt(100^2+100^2)
Therefore, Z=200. Right?
Therefore, Z=200. Right?

z=sqrt(R^2+X^2),then z=sqrt(100^2+100^2)
therefore z=sqrt(20000) so implies sqrt(10000*2)
100sqrt(2) i.e100*1.414=141.4
therefore z=sqrt(20000) so implies sqrt(10000*2)
100sqrt(2) i.e100*1.414=141.4

Z = R+jXL.
Then convert it into polar form.

R = 100 XL = 100.
Z = sqr(100*100+100*100) = sqr(20000) = 141.4 ohms.
Z = sqr(100*100+100*100) = sqr(20000) = 141.4 ohms.

Another way to express this is due to Resistor and Inductance current flow are not in the same phase they can be shown as below. Total impedance cannot be plus but use trigonometric equation,
Z^2 = Xl^2 R^2.
Z = sqr(Xl^2 R^2).
Z = sqr(100 * 100 + 100 * 100) = sqr(20000) = 141.4 ohms.
Z^2 = Xl^2 R^2.
Z = sqr(Xl^2 R^2).
Z = sqr(100 * 100 + 100 * 100) = sqr(20000) = 141.4 ohms.

z = sqrt(r squared +XL squared),
Substituting values,we have;
z = sqrt(20000),
z = 141.4ohms.
Substituting values,we have;
z = sqrt(20000),
z = 141.4ohms.

Z =√(r^2*+l^2).
=√(100*100+100*100).
=√(20000).
=141.4.
=√(100*100+100*100).
=√(20000).
=141.4.

z= √(r^2+Xl^2).
=√(100^2+100^2).
=√20000).
= 141.4.
=√(100^2+100^2).
=√20000).
= 141.4.
